I don't think I've ever played a game where I found it to feel better at a lower framerate. The lower the FPS, the highter the latency of input response and the lower temporal resolution makes it harder to track movement, particularly rotational control of a camera.

Artistic intention I do understand. I played your game and you're specifically evoking a low-fi aesthetic. The noise in particular might look noiser at higher framerates, damaging the era it's trying to evoke.

Though I have to wonder if there might be a way to split the difference, to render out the scene at low FPS and reproject the camera at a higher framerate, similar to how most VR implementations work. That way the aesthetic would be largely unchanged, if the camera isn't moving it would be identical, but you'd get that much nicer input response.
